Do you know laser pointer technology?
In 1917, Einstein put forward a new theory of laser pointer technology, which is called "the interaction between light and matter", that is, the number of particles (electrons) At the high energy level, particles are stimulated by certain photons, The transition from high energy level (transition) to low energy level is to excite light with the same characteristics, In some countries, weak light can cause strong light "Stimulated lighting right" or laser. In recent years, high efficiency laser technology has become one of the most popular research fields in the field of optoelectronics, especially laser technology. After nearly 30 years of exploration, it changes with each passing day and is widely used in medicine, scientific research, informatization, military and other fields, Defense and other areas.

The so-called Laser pointer technology is to research and develop the manufacturing method, research and application of laser, Laser technology and applications have developed rapidly in the past 50's, and a series of applications have been created in combination with different disciplines, such as, Such as optoelectronics and Photobiology, laser medicine, laser processing technology, laser detection and measurement technology, laser holography, laser spectroscopy, Nonlinear optics and ultra high speed laser, laser chemistry, quantum optics, lidar, laser admittance, laser isotope separation The emergence of these interdisciplinary technologies and new disciplines has greatly promoted the development of traditional and emerging industries. For example, Laser surgery has small incision, little or no tissue damage and less toxic and side effects, At present, laser myopia is used in clinic, including retinal repair and dental caries repair, At present, the best applied research in the field of laser medicine is shown in the following fields: photodynamic cancer treatment; Laser treatment of cardiovascular diseases; Excimer laser corneal transplantation; Laser cosmetic surgery; Laser beam endoscopy; Cheek laser surgery; Thoracoscopic laser surgery; Laser laryngoscopy; Laser engraving machine; Laser surgery; Application of laser in matching; Application of laser in dentistry, face and dental surgery; At present, laser therapy has developed steadily in the fields of basic research and new technology development, Development and production of new plants.
